I don't know: the earliest kernel this machine has ever run was 2.6.30rc5, and this failing 2.6.30rc7 kernel is the first 64-bit kernel I've ever run on it. So currently I have one single data point.
I plan to try out 2.6.29 (and back to 2.6.25 or thereabouts) tomorrow and see if it ever worked: if it did I'll bisect for it (rendered tricky by the out-of-tree e1000e driver, but doable: it would be easier if I had a clue where the e1000-devel git tree is, if anywhere, but I still have no idea despite considerable searching).
It seems to go wrong instantly, so replication is trivial, and this system can compile a kernel in slightly under a minute, so it shouldn't take too long to complete the bisection.
